1 Product Overview
BT3L-G is an embedded Bluetooth Low Energy (BLE) module that Tuya has developed. It
consists of a highly integrated Bluetooth chip (TLSR8250F512GT32) and several
peripheral circuits, with an embedded Bluetooth network protocol stack and robust library
functions. BT3L-G also contains a low-power 32-bit multipoint control unit (MCU), BLE 5.0
or 2.4 GHz radio, 4 MB flash memory, 48 KB static random-access memory (SRAM), and
nine multiplexing I/O pins.
1.1 Features
 Embedded low-power 32-bit MCU, which can also function as an application
processor

 Working voltage: 1.8 V to 3.6 V (Under 1.8 V to 2.7 V, the module can start but the RF
performance is not guaranteed. Under 2.8 V to 3.6 V, the module performance is
normal.)
 Peripherals: nine pulse width modulation (PWM) pins
 BLE RF features
 Compatible with BLE 5.0
 Up to 2 Mbit/s RF data rate
 TX power: +10 dBm
 RX sensitivity: –94.5 dBm at BLE 1 Mbit/s
 Embedded Advanced Encryption Standard (AES) hardware encryption
 Onboard PCB antenna
 Working temperature: –20°C to +105°C
